Binary!

[grande]

Is there an easy way to convert a number to binary? Perhaps something similar to the %x for Hex?

You could use a bitset:

#include <iostream>
#include <bitset>

int main()
{
    //                     1   1   0   0   1   1   0   0   1   1
    unsigned long value = 512+256+ 0 + 0 + 32+ 16+ 0 + 0 + 2 + 1;
    std::bitset<12> bits(value);

    std::cout << "Decimal: " << value << std::endl;
    std::cout << "Binary : " << bits << std::endl;
}

Notice that you have to specify the number of bits, and all bits are output in this example, including leading 0's.

Or you can use the old itoa(...) function with radix = 2
